Ph.D. Aeronautics and Astronautics, Stanford University, Palo Alto, CA

M.Sc. Aeronautical Engineering, Delft University of Technology, Delft, Netherlands

Research Interests

Mechanics of solids; quantitative nondestructive evaluation and fracture mechanics In recent years, Professor Achenbach has developed methods for flaw detection and characterization by using contact transducers, imaging techniques, and laser-based ultrasonics. He has also developed methods for thin-layer characterization by acoustic microscopy. Work is both analytical and experimental in nature, with extensive cooperation with investigators from other universities and from industrial organizations on theoretical experimental projects. Work in fracture mechanics has been primarily on dynamic fracture. He also carries out research on structural acoustics and on the mechanical behavior of composite materials.
